The Royal Academy of Arts has elected the imprisoned Chinese artist Ai Weiwei as an honorary member on the eve of its Summer Exhibition, the largest and oldest open art exhibition in the world and a fixture in the arts calender since 1768.

This year's stars include the Jeff Koons Coloring Book sculpture in the courtyard; Work No. 998, a stack of chairs by the Turner prize winner Martin Creed; and a sculpture by Richard Wilson inspired by the film The Italian Job, called Hang on a minute lads, I've got a great idea.

The hundreds of works have been chosen from 12,000 submitted from 27 countries. The show opens on 7 June and runs until 15 August .

The exhibition is the largest open contemporary art exhibition in the world, drawing together a wide range of new and recent work by established, unknown and emerging artists, and runs in London from 7 June to 15 August
